It is Well known in the nrt, that clocks subject to temperature Change will vay from their piopeil setting, goingl eitheix Atast or slow according' to the change in temperaA ture. The usual manner of Coiiecting for such variations by adjusting 'the oscillations of the estapetnent. n a clock having a balance or pendulum spying for controlling the escapeinent. this correction is commonly mmle by adjusting the tension ot' such spring. lVhere a pendulum is employed, ie'coifeotion is inatle by adjusting the length of l pendulum. l lintl that in oitlei" to @fopen iegulahte a time piece and to man" )loper iegulation, a manual t. l; an automatic adjustment are ne@ "y, 'lie prior art pio'visions 'tot' ineef ,j quireinents lnve been Complex anti sive.

meonsnisni i niounetl utf suitnbin hase. 1. is adapted to be intcaseu in a ove1 oi Casing foi'metl of glass ani] llO up of the usual spring motor and escapement mechanism mounted upon shafts secured in a vertical front frame plate 4 and a similar rear plate (not shown). Springs (not shown) housed within suitable barrels to the rear of the gears 5 and 6 furnish the power for driving the anchor escapement member 7 through an escapement wheel 8 and the usual intermediate driving train including the .necessary gears and pinions The anchor escapement-has suitable driving connection with a balance shaft 9, so that such shaft will be oscillated with the oscillations of the escapement member 7. The tension of a coiled balance or pendulum spring 10 controls the speed of escapement of the movement as well understood by those skilled in the art. The inner end of the-- coiled spring 10 is secured to the balance shaft 9. The outer end of the spring 1() is Adried in a bracket member 11 secured' to and eit'ending rearwardly from the front frame plate L1.

The forward end of the balance shaft 9 bears in a stud 12 mounted in thev frame plate 4 adjacent the upper edge thereof. An arm 13 loosely mounted upon the shank of the stud 12 adjacent the Jfront face of the frame piece 4 extends upwardly and carries a rearwardly extending finger 14 at its upper end.I This rearwardly extending linger 14 coperates'with the, balance spring 10 to vary the tension and thereby the vibrations thereof as well understood in the art when the arm '13 is swung about the shank of -the stud 12 as will be hereinafter explained.

The shaft 9 may be provided with the usual balance wheel 15 and the driving connection between the anchor escapement and the shaft 9 may be had through this balance wheel if so desired. A finger 16 ixedly secured to the arm 13 and extending forwardly therefrom is provided at itsforward end with an eye throughv which eye the.

rearwardly bent upper end 17 off the main adjusting arm 18 extends.; j

f The lower end of the adjusting arm 18 is connected at 19 with the downwardly extending outer 'convolution of an automatic 'regulating or adjusting member 20. The automatic adjusting member 20Ieomprises lamina or strips 21 and 22 (Fig. 2) of two metals having different co-eflicients of expansion suitably secured together and coiled or turned up into a spiral. The inner end of this coil or spiral 20 is tixedly secured to a stud or pivot 23. Thel reduced shank of the stud or pivot 23 extends through a mounting piece or plate 24e carried by the frame 4 in proper spaced relation therefrom and is headed over as shown.

The Vertical portion of the adjusting arm Y18 extends through an eye 25 carried by one cr-d of an angle lpiece 26. The eye 25 provides the pivot about which the arm 18 is rescues swung as will be hereinafter explained to vary the tension of the balance spring 18 and thereby the rate of escapement of the movement. A slotted mount-ing base 27 at the opposite end of the angle piece provides for adj ustably mounting the same upon the plate 24 through a suitable set screw 28. Obviously, by the vertical adjustment of the angle piece 26, thereby provided for7 the posit-ion of the pivot 25 about which the arm 18 is swung maybe varied. Threaded openings 29 in the plate 2e provide for changing the position of the set screw28 to still further increase the range of adjustment of the'eye or pivot 25.

It will now be apparent, the lamin 21 and 22 of the automatic adjusting member I 2O having different degrees of expansion under the same temperature, that a change in temperature will swing the outer convolution of the coiled member 2O either outwardly or inwardly (depending upon Jdie temperature change) swinging the arm 18 through the connection 19 about its pivot 25. The movement of 'the nger 14 upon such swinging of the arm 18 vserves vto increase or decrease the tension of the spring .10 to counteract the effect of a temperature change upon the movement. For example, if the temperature change is such as to cause the movement to lose one second in every sixty, the automatic regulator'is adjusted so that it will when subjected to such tem-v perature increase the speed of the movement one secondin every sixty, thereby compen-` sating for or counter-acting theeffect of the temperature change upon the movement.

A very fine adjustment ofthe' automatic regulator for'a certainl temperature change may be quickly and conveniently had by adjusting the position of the pivot 25 as hereinbefore set forth. By adjustment of such pivot, lthe proportion lbetween the length of arm 18 below such pivot and the length of arm 18 abovel such pivot may be varied to vary the amount of swing of the finger 14 and consequently the amount of adjustment of the spring 10 for a given swing of the connection 19.

An arm 35 fixed at its inner endto the stud 234 for rotation therewith is provided with agnger piece 36 at its outer end, This arm provides for manual adjustment of icc ros

the movement', swinging of such arm 'ro'tat- /ing'the stud 23 which rotation is thereupon imparted through the coiled automatic adjusting member 20 to the lower end of the i naaien j for example', which are necessarily subjected to'severe andvarying Weather conditions.
